We have observed the star GSC 01060-01374 to investigate whether it is in a binary with PSR B1929+10. Its spectral type is K4-6 and its luminosity class is III or II, therefore its distance is 2.4 kpc or higher. Since the dispersion measure distance of PSR B1929+10 is 0.17 kpc, we rule out the possibility that these two stars are associated in a binary. This poses further constraints on the lower limit of kick velocities in supernova explosions.

Key words: stars: individual: GSC 01060 -- 01374 -- stars: neutron -- pulsars: individual: PSR B1929+10
